Syn: Minuartia mesogitana
Decumbent to ascending or ± erect annual, up to 20 cm, branching from the base, glabrous below. Leaves linear-subulate to subulate-setaceous, 3-veined, never fleshy. Inflorescence sparsely glandular-pubescent, of several lax, many-flowered dichasia; bracts triangular to subulate, prominently 3-veined; pedicels 8-20 mm, more than 3 x longer than sepals, often spreading widely. Sepals 1,5-4 mm, usually ovate to ovate-lanceolate, acute, rarely lanceolate, acuminate, 2-3 x longer than broad. Petals ovate to ovate-lanceolate, usually abruptly contracted at base into a very short claw, 0,9-1,3 x longer than sepals. Capsule subglobose to subcylindrical, almost as long to much longer than calyx. Seeds 0,25-0,7 mm.
